Less Common Types of Variables Active Variable: a variable that is manipulated by the researcher. Antecedent Variable: a variable that comes before the independent variable. Attribute variable: another name for a categorical variable (in statistical software) or a variable that isn’t manipulated (in...
First, we illustrate the role of dependent and independent variables. Second, we discuss the difference between experimental and non-experimental research. Finally, we explain how variables can be characterised as either categorical or continuous....

Here are some of the commonly used methods for data analysis in research. Correlation: When researchers are not conducting experimental research or quasi-experimental research wherein the researchers are interested to understand the relationship between two or more variables, they opt for correlational ...

We propose a method to map uncertainty zone of interpolated categorical variable. We transform categorical variable types into indicator functions for interpolation. Interpolation variance (InV) can be used to map the uncertainty zone. InV is a component of total variance, as measured by coefficient ...
Purpose To find out whether the association between two categorical variables are statistically significant Null Hypothesis There is no association between two variables Prior to using the chi square test, there are certain requirements that must be met. The data must be in the form of frequen...
Categorical DataCategorical data represent discrete, qualitative information that can be divided into specific categories or classes. It does not have any inherent numerical meaning. Examples of categorical data include gender (e.g., male or female), color (e.g., red, blue, or green), and ...
